Simple question yet no clear answer - X01

Unfortunately it depends who setup your bike. Did the person give the chain length room to go bigger or did the person make the chain short. You probably won't know until you put a larger cog on. I guess you could also put your bike in the largest cog in the rear & let all the air out of the shock & see how much slack you have. It you've got slack then you probably have enough chain, but you'll still need to check.
